Abstract

The present invention relates to an absorbent wound dressing which comprises a layer of hydrophobic silicone gel (3) which is intended to lie against the wound surface when the dressing is worn, a layer of carrier material (2; 7) which carries the gel layer and affords the requisite strength thereto, and an absorbent body (5) which is placed on that side of the carrier material end gel layer which lie distal from the wound surface in use, wherein the carrier material and the gel layer have mutually coinciding penetrating perforations (4) at least within the region of the absorbent body.
According to the invention, a fluid barrier layer (6) is provided on that side of the dressing which lies distal from the wound surface in use.
